1t-claims. (014314246) `This invention relates generally to asmokers article but more particularly to improvements in an electrically roperated device or appliance for cleaning thebowls of smokingpipes.

It has for one of its objects to provide a device of this character for domestic use whichv is designed to not only effectually clean the cake from the pipe bowl but which will conduct the scrapings by an air draft intoa receiver and thereby prevent the dust and scrapings escaping into the attion forl cleaning. Figure 3 is a horizontal section Figure 2 is an enlarged central vertical section thereof showing a pipe in positaken on line 3 3, Figure 2.' Figure 4 is a simie lar section taken on line A4-4,Figu re 2. Figure 5 is a fragmentary end view ofthe bowl-cleaning f element. 1

Similar characters of reference indicate correspending parts throughout the several views.

In the preferred embodiment of the invention shown in the drawing, ID indicates a body forming an ash receiver for the scrapings removed from the pipe bowl, the same being substantially cylindrical in form and having a supporting Vbase I I at its bottom and a detachable cover I2 at itsftop. The connection between the receiver and its cover maybe in the form of a bayonet or like joint, such joint including the complementary pin and Vslot elements I3 and I4, respectively.

Rising from the cover I2 is a hood or enc1osure I5 having inner and outer chambers I6 and I'I, respectively, such chambers being divided by a tubular member I8 which is detachably connected adjacent its lower end to a central collar I9 formed on the cover and joined thereto by a bayonet or like joint including the pin and slot elements 20, 2 I. The lower end of this tube forming the inner chamber I6 opens into the ash receiver I0 to'conduct the bowl-scrapings thereto, while the pipe bowl 22 is adapted to ibe inserted into the upper end of this chamber in the manner shown in Figforming tube Iais an adjustable guard or cover 23 Whose skirt 24 has .a bowl-receiving opening 25 in the side-wall 'thereof and through which opening Y' the pipe bowl is adapted to be inserted and removed before and after cleaning operations. In

"escape ofl the obnoxious odors emitted. from the pipe-scrapings deposited into the receiver I0. As shown in Figure 2, the upper end of the'tube I8 is 'preferably ared so that when introducing the pipe in an Vinverted position into the device the ashes will be properly deilected downwardly in to the receiver.

Depending from the cover l2 about the lower end of the tube I8 and partially into the receiver I0 are a plurality of spaced radially-disposed arms 26 which terminate at their lower ends in inwardly-facing lugs 21 and which are adapted to support an electric motor `28 in the manner shown in Figure 2; Connected to these arms is a clamping band 29 which is adapted .to extend around the motor housing to securely retain it in place between thearms. The motor shaft 30 extends upwardly therefrom axially of the receiver and the aliningr tube I8 and has mounted thereona down draft or suction-creating means which may be in the form of. a fan 3| drawing the ibowl-scrapings downwardly into theash receiven Disposed in `axial alinementwith the motorgshaft `andcoupled thereto bya collar 32, is the revolving spindle 33 of a cleaning element 34 which is located in the upper end of the inner chamber I6 of the enclosure I5 and with which the bowl of the pipe is engageable for cleaning the same. This cleaning 1 element is preferably in the form of a circular wire brush mounted on a horizontal axis in thebifurcated upper end 35 of the spindle 33. This brush functions as a reamer in cleaning the bowl of the pipe and it can be adjusted on its axis when desired and thereby affords a fresh surface for cleaning purposes.

The cover I2 is provided in its top and about the collar I9 thereof with an annular row of openings 36 to establish communication between the receiver II! and the outer enclosure chamber I1 and to thereby provide for the venting of the receiver during the operation of the device. This outer chamber is in turn provided adjacent its lower end with an annular row of vent openings 31 formed by slitting the marginal edge of the enclosure and providing resulting inwardly-bent ure 2.` Telescopically fitted within the chamber- 55 lugs 38 which are spaced above the top of the cover I2 in the manner shown in Figure 2. Resting on the cover over its openings 36 and about its collar I9, is a ring-shaped ltering element or screen 39 which is retained in place along its marginal outer edge by the lugs 38 and along its marginal inner edge by the coupling pins 20 of the bayonet joint which detachably connects the tube I6 with the cover-collar. This iiltering element may be made of glass wool, cloth, felt or like material and it may be impregnated with a.

deodorant to eliminate the obnoxious odors escaping from the receiver I and vented through the cover I2 and enclosure I5 when the device is in operation. A deflector 4I) of substantially conical shap is disposed about the shaft 30 between the motor 28 and the fan 3I for directing the bowl scraping downwardly and outwardly into the receiver lil. As shown in Figur-es 2 and`4, the deflector is notched at 4I to embrace the motor-supporting arms 26 and thereby effectually retain it in position.

In use, the guard 23 is elevated and the pipe bowl inserted through its opening 25 into engagement .with the cleaning brush 34, as shown in Figures l and 2, and the motor started to operate the brush and the fan 3|. The ashes and scrapings removed from the bowl are drawn downwardly through the chamber I6 and into the receiver Ill by the suction of the fan, the receiver being vented through the filtering element 39 and thence into the atmosphere through the vent openings 31.

When it is desired to empty the contents of the receiver I Il, the cover I 2 and parts borne thereby are removed by disconnecting the joints 3, It. Should it be desired to renew the ltering element, the hood I and parts borne by it are disconnected from the cover-collar I9 by breaking the joint 20, 2I.

I claim as my invention:
